Titanium alloy screws are easy to rust in the exposed air, so titanium screws need to do some work to prevent moisture and humidity. The following is a specific analysis for everyone.
1. Selection of component insulation dipping paint, such as epoxy resin or polyurethane dipping paint. Choose paints that do not contain volatile acids. Vibration machinery uses solvent-free paint.
2. For the use of melamine alkyd paint, the fixed-line temperature and fixed-line time should be adjusted. The fixed-line temperature is slightly higher than 130 degrees and the fixed-line time is greater than 180 minutes. It is necessary to strictly implement the process, especially In the hot and humid season, from a rusty point of view, the regular drying time of the paint factory is not necessarily, and has a specific internal shape.
3. The surface corrosion treatment of titanium alloy screws refers to the use of various methods to exert the maintenance layer on the metal surface. The function is to isolate the metal from the corrosive environment to inhibit the corrosion process or reduce the contact between the corrosive medium and the metal surface to prevent or slow down the corrosion purpose.
At the same time, special attention should be paid to the selection technology of screw material:
1. The mechanical properties of the screw material, especially the strength requirements. Titanium alloy screws require a relatively high strength, the higher the strength of the selected screw material itself.
2. Requirements for corrosion resistance of materials under working conditions. Some of the screws are used in the above-mentioned products with strong corrosion, and it is necessary to select the corrosion resistance of the strong spiral steel wire.
3. Requirements for the working temperature of the material's heat resistance. When some screws are used in high temperature operation, it is necessary to select the high temperature performance of the screw material.
4. Performance requirements in the production process of material processing. Some screws are better processed in the production process, requiring the appropriate hardness of the screw material, which is conducive to processing and production.
5. Other factors, such as weight, price, and purchase considerations. The weight, price, purchase and other factors of the titanium alloy screw itself affect the choice of screw material
